This project contains helpers used at the ENSAE for teachings available at ENSAE - Programmation - Xavier Dupré. It was the first module created for that usage. It does not have a clear purpose except hiding some annoying logic and shorten notebooks. It can:

  • retrieve data for practical lessons

  • import a tsv file into a database

  • retrieve stock prices from Yahoo Finance

It implements a couple of magic commands to play with SQLite3 in a notebook and easily show the head or tail of a text file. It can fill missing values in timeseries with add_missing_indices or download data from a website, a helper to change the size of folium maps or some grammar to parse language such as R or SQL. It also implements a basic way to convert a R script into nasty Python.
